+mbuffer (a tool for buffering data streams)
+
+mbuffer has a large set of unique features:
+  - direct support for TCP based network targets (IPv4 and IPv6)
+  - ability to send to multiple targets in parallel
+  - support for multiple volumes
+  - I/O rate limitation
+  - high/low watermark based restart criteria
+  - configurable buffer size
+  - on the fly MD5 hash calculation
+
+It is especially useful, if you are writing backups to fast tape drives
+or libraries. Those drives tend to stop and rewind if they have a buffer
+underrun. This so called tape screwing reduces the lifetime of the
+motors.
+
+mbuffer can prevent buffer underruns, if used correctly and speed up
+the whole backup process. Please read the man page for details, how to
+use it.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
